To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
I needed a metal trivet for my wood stove for putting pots on for cooking & keeping food warm. Works great & is pretty. Was concerned about the rubber feet on the stove, but has been fine. Held up well.
